644960 divided by 19 
Let's see how many times 19 fits into 644960.

Advancing to step 1:
The number 19 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 19

Let's proceed to step 2:
When dividing 64 by 19, we get 3 with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 57 from 64 to get 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 19

Advancing to step 3:
19 goes into 74 3 times with a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 33.0
If we take 57 away from 74, we end up with 17.
Grab the next digit (9) from the dividend, add it to 17, then carry on: 179 / 19

Moving on to step 4:
19 goes into 179 9 times with a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 339.0
Subtract 171 from 179 to get 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 19

Moving on to step 5:
19 goes into 86 4 times with a remainder of 10.
The next digit of our result is 4. 
Result so far: 3394.0
If we take 76 away from 86, we end up with 10.
Append the next digit (0) from the dividend to 10 and continue with: 100 / 19

Step 6:
If we divide 100 by 19, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 33945.0
The remainder is 5 after subtracting 95 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 7:
19 can be fit into 50 2 times, resulting in a remainder of 12.
The next digit of our result is 2. 
Result so far: 33945.2
The remainder is 12 after subtracting 38 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 8:
19 can be fit into 120 6 times, resulting in a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 33945.26
If we take 114 away from 120, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 9:
When dividing 60 by 19, we get 3 with a remainder of 3.
The next digit of our result is 3. 
Result so far: 33945.263
If we subtract 57 from 60, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 10:
19 can be fit into 30 1 times, resulting in a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 33945.2631
The remainder is 11 after subtracting 19 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 11:
When dividing 110 by 19, we get 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 33945.26315
If we take 95 away from 110, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 12:
If we divide 150 by 19, we get 7 and a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 33945.263157
Subtract 133 from 150 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 13:
19 goes into 170 8 times with a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 33945.2631578
Subtract 152 from 170 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 14:
19 goes into 180 9 times with a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 33945.26315789
If we subtract 171 from 180, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Our division results in 33945.26315789 with a remaining 9e-09.
